3.8 Setting a Vertical Window of Interest
A window of interest is a subset of a full frame image that is desired as output from the camera. Because
the sensor is outputting only the designated window of interest, the benefit is an increase in frame rate
and a reduction in data volume. You can set both the horizontal and vertical window, however only
decreasing the vertical window increases the frame rate.
